【摘要】 本文根据深圳市前海地区2015~2017年间地下水位的监测资料,分析了填土(石)层水位、砂层承压水水位和基岩裂隙水水位的动态特征,发现砂层承压水水位和基岩裂隙水水位区别不明显,填土(石)层水位与另外两种水位相差较大。填土(石)层水位的变化特征主要为气候型,砂层承压水水位和基岩裂隙水水位的变化特征主要为水文型,二者均受到工程开发中降水的影响。并应用频谱分析法对前海地区的地下水位变化进行了分析,建立了地下水位预测模型,分析预测了前海地区在未来一段时间内最高地下水位可能的变化趋势,为本区域的工程建设提供一定参考。

【Abstract】 Based on the monitoring data of groundwater level in Qianhai area of Shenzhen from 2015 to 2017, the dynamic characteristics of water level in fill/rockfill layer, sand layer and bedrock fissure are analyzed in this paper. It is found that the difference between water level of sand layer and the rock fissure is not obvious, but the water level in the fill/rockfill layer is quite different from the others. The dynamic characteristics of the water level in fill/rockfill layer can be described as climatic type. The dynamic characteristics of sand layer bearing water level and bedrock fissure water level can be described as hydrological type. Both are affected by dewatering of engineering development. The spectrum analysis method was applied to analyze the changes of water level in Qianhai area, and the prediction model was established for groundwater development trend that may occur in the Qianhai area in future. The results could be referred by the engineering construction in the region.
